Description

Pit digging device for peony planting

Technical Field

The utility model relates to the technical field of pit digging devices, in particular to a pit digging device for peony planting.

Background

When the paeonia lactiflora is planted, a pit is dug on the ground, and then the paeonia lactiflora is planted in the pit. In the prior art, a planter generally uses a portable pit digger to dig pits, and specifically, the planter holds two handles of the portable pit digger with hands, then presses the portable pit digger downwards after the pit digger is started, generally holds the portable pit digger to prevent the portable pit digger from tilting, and after a pit with enough depth is dug, the planter forcefully lifts the portable pit digger.

It is clear that the existing portable pit digger has the following three obvious defects in use:

1. when digging pits, the manual support of the planting personnel is needed to ensure that the portable pit digger cannot incline, otherwise, the dug pits can be askew and do not meet the planting requirement of the Chinese herbaceous peony;

2. when digging a pit, a planter is required to exert force to press the portable pit digger downwards, and after the pit digging is finished, the planter is required to lift the portable pit digger upwards with force, so that the labor is wasted;

3. when digging the pit, a large amount of soil can appear and splash everywhere, be unfavorable for later stage landfill, and also dirty planting personnel's clothes easily.
